Maybe this is a trendlet, but I've noticed a couple of eateries expanding their hours of service. 
Rae, in the Cira Centre (at left), has added breakfast from 7 to 10 a.m, effective Monday 9/17. Cantina Los Caballitos, the Mexican on Passyunk Avenue in South Philly, just started weekday lunch, and it runs from noon all the way to 5 PM, when the dinner menu kicks in. And Cantina's Sunday brunch goes all the way to 4 p.m. Georges’, Georges Perrier’s joint in Spread Eagle Village in Wayne, put on Saturday lunch from 11:30 to 2:30, which it then follows with a so-called midday menu till dinner starts at 5.
